   7         help
   8           Say Y here if you are compiling the kernel on a different
   9           architecture than the one it is intended to run on.

  11 config CMDLINE
  12         string "Default kernel command string"
  13         default ""
  14         help
  15           On some platforms, there is currently no way for the boot loader to
  16           pass arguments to the kernel. For these platforms, you can supply
  17           some command-line options at build time by entering them here.  In
  18           other cases you can specify kernel args so that you don't have
  19           to set them up in board prom initialization routines.

  21 config DEBUG_STACK_USAGE
  22         bool "Enable stack utilization instrumentation"
  23         depends on DEBUG_KERNEL
  24         help
  25           Enables the display of the minimum amount of free stack which each
  26           task has ever had available in the sysrq-T and sysrq-P debug output.
  27
  28           This option will slow down process creation somewhat.

  33         select DEBUG_INFO
  34         help
  35           If you say Y here, it will be possible to remotely debug the MIPS
  36           kernel using gdb. This enlarges your kernel image disk size by
  37           several megabytes and requires a machine with more than 16 MB,
  38           better 32 MB RAM to avoid excessive linking time. This is only
  39           useful for kernel hackers. If unsure, say N.

  42         bool "Console output to GDB"
  43         depends on KGDB
  44         help
  45           If you are using GDB for remote debugging over a serial port and
  46           would like kernel messages to be formatted into GDB $O packets so
  47           that GDB prints them as program output, say 'Y'.

  54           Select compile flags that produce code that can be processed by the
  55           Corelis mksym utility and UDB Emulator.

  58         bool "Enable run-time debugging"
  59         depends on DEBUG_KERNEL
  60         help
  61           If you say Y here, some debugging macros will do run-time checking.
  62           If you say N here, those macros will mostly turn to no-ops.  See
  63           include/asm-mips/debug.h for debuging macros.
  64           If unsure, say N.
  65
  66 config MIPS_UNCACHED
  67         bool "Run uncached"
  68         depends on DEBUG_KERNEL && !SMP && !SGI_IP27
  69         help
  70           If you say Y here there kernel will disable all CPU caches.  This will
  71           reduce the system's performance dramatically but can help finding
  72           otherwise hard to track bugs.  It can also useful if you're doing
  73           hardware debugging with a logic analyzer and need to see all traffic
  74           on the bus.
